CC3220MODA: WiFi direct and WPA2

Part Number: CC3220MODA
Other Parts Discussed in Thread: CC3200, UNIFLASH

Hi,

I have a question from my customer about WiFi Direct and WPA2.
They wants to use WPA2 for WiFi direct connection with password.

According to below E2E threads, WPA2 is automatically used to establish P2P connection in CC3200.
I guess it is similar to WiFi direct in CC3220.

http://e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/607995

If so, what customer needs to do are;
- secParams.Type = SL_WLAN_SEC_TYPE_PIN_KEYPAD
or SL_WLAN_SEC_TYPE_P2P_PIN_DISPLAY
- secParams.Key = “abcdefgh” (password customer wants to use)

Then WPA2 will be used to make Wifi direct connection.
Correct? Can we use non-numerical value for sec.Params.Key ?

Thanks and regards,
KoT

Hello,

Correct, WPA2 is used once a WiFi-Direct connection is established.

I believe it does not matter if the key is a number. Whatever you give it, it still gets stored as 1's and 0's. Just make sure the customer encodes their keypad inputs to whatever key value is expected.

Hi Jesu
I am sorry that the reply was delayed.
I asked KoT a question on this thread.

I am using the Cloud_ota sample to test the project.
Unfortunately, the method that you and KoT advised could not be confirmed in the sample project.
However, I think that Security and Password can be set in "DevelopmentMode - AP & Wi - Fi Directory Group Owner WLAN Configurations" on UniFlash setup screen, is not it?

Thank you.

Hello,

I'm not sure what the question is. Have you gotten WiFi direct working and want to know if the KEYPAD security feature support non-numeric? I don't see how your previous question relates to the original question.

Mr. Jesu

The first question I was asking was the state when connecting the smartphone and the CC 3220 for the first time in Provising.
Since CC3220 at this time was OPEN secur by default, I asked how to change to WPA 2.
Did I misunderstand how to use "Wi - Fi Direct"?
I'm sorry I let you use wasted time.
